Description

Bending modulus material turnover discharging mechanism

Technical field

The utility model belongs to the Stamping Die Technology field, is specifically related to a kind of Bending modulus material turnover discharging mechanism.

Background technology

Along with technology of die manufacturing improves constantly, mould structure becomes increasingly complex, and often occurring can't in the mould

The space of the manual pickup of reservation operations people.Because the increase of machine-shaping content causes the action request that takes out product to increase, when die presses down was curved, the picking-up frame of straight flange that product is downward and product was interfered, and causes product normally not skid off.

Common rotation discharging mechanism is to be fixing point with the rotating shaft at present, if product is slipped out on location-plate

Mould needs the stroke of pneumatic picking-up mechanism action very big, because the height of mould closure is limited by the press machine shut height, causes the stroke height that holds up mechanism to be restricted.Be illustrated in figure 1 as the structural representation of press machine upset discharging mechanism in the prior art, because in bending die, often there is the product U-shaped to bend, both sides are translated into 90 ° of straight flanges downwards, because of press-bending punch working portion needs, material supporting rack 10 must be in the middle of the downward straight flange in product 9 both sides, straight flange retaining after the bending makes product 9 skid off mould from material supporting rack 10 on material supporting rack 10, if increase the slip angle of material supporting rack 10, can cause product 9 to skid off apart from very little, product 9 can be run into location-plate 4 after material supporting rack 10 skids off, product 9 can't be discharged from mould; If reduce slip angle, the gravity of product 9 can not overcome the frictional force with material supporting rack 10, and product 9 can not move.

The upset discharging mechanism can be verified needs according to mould, adjusts the material supporting rack rotational time, and conventional upset discharging mechanism is that rotating shaft is fixed, and perhaps the motion control pin is fixed in the chute of circular arc, determines and can't adjust during the movement locus design.

The utility model content

Technical problem to be solved in the utility model is the above-mentioned defective at prior art, and a kind of Bending modulus material turnover discharging mechanism that solves the curved part discharging problem of die presses down is provided.

The technical scheme that solution the utility model technical problem is adopted is this Bending modulus material turnover discharging mechanism, comprise upset discharge rack, upset return pull bar, cylinder, location-plate, upset return pull bar connects together by rotating shaft with an end of upset discharge rack, this discharging mechanism also includes swing arm and upset pull bar, the lower end of swing arm links to each other with cylinder, its upper end links to each other with the upset discharge rack, and the upset pull bar links to each other with the other end of upset discharge rack.

Adopt the utility model, product can turn over the location-plate that jumps when product is discharged, thereby has solved the problem of press-bending part discharging.

The utility model can be widely used on the stamping line, has avoided expecting recurrent security incident also to have reduced operating personnel simultaneously owing to manually getting in the stamping press.

Description of drawings

Below in conjunction with the embodiment accompanying drawing, the utility model is described in further detail.

Among the figure: 1-cylinder 2-upset return pull bar 3-swing arm 4-location-plate 5-upset discharge rack

The specific embodiment

In the present embodiment, this discharging mechanism comprises upset discharge rack 5, upset return pull bar 2, cylinder 1, location-plate 4, swing arm 3, upset pull bar 7, the end of return pull bar 2 and upset discharge rack 5 of wherein overturning connects together by rotating shaft, and upset pull bar 7 links to each other with the other end of upset discharge rack 5.The lower end of swing arm 3 links to each other with cylinder 1, and its upper end links to each other with upset discharge rack 5.There is upset returning pull-spring 8 upper end of upset return pull bar 2, its effect is to make upset discharge rack 5 returns after the discharging process finishes, all there is limited block 6 lower end of upset return pull bar 2 and upset pull bar 7, limited block 6 is the adjustable sleeve in position, can slide up and down, limited block 6 is used for adjusting flip angle, when adjusting the position of upset pull bar 7 upper limit position blocks 6, adjust the limited block 6 on the upset return pull bar 2 simultaneously, make upset consistent with return.The process of adjusting limited block 6 is as follows: during position of every adjustment, can be by the locking of the lock-screw on the limited block 6, when limited block 6 is adjusted to the appropriate location, can turn over the location-plate 4 that jumps from upset discharge rack 5 smoothly until product 9 skids off outside the mould, boring on upset return pull bar 2 again, make lock-screw pass the sidewall locking limited block 6 of upset return pull bar 2, with assurance in the course of the work, the position of limited block 6 is constant all the time.

The course of work of the present utility model is as follows:

When the mould part on press machine is closed, upset discharge rack 5 is arranged in the groove of dodging of bending die punch, mold open when press-bending is finished, the material carrying mechanism of cylinder 1 moves upward, promote upwards moving linearly of upset discharge rack 5, upset discharge rack 5 moves to position B from position A, with the product 9 vertical vertical side edge of punch and the vertical components of location-plate 4 of throwing off, when the picking-up mechanism of cylinder 1 moves to predetermined altitude vertically upward, in the present embodiment 200mm, limited block 6 on the upset pull bar 7 touches following limit for height face, upset pull bar 7 stops to move upward, and cylinder 1 and upset return pull bar 2 continue to move upward, so just make 5 upsets of upset discharge rack, swing arm 3 simultaneously is to location-plate 4 one side oscillations, and the pivot of upset discharge rack 5 moves to the outside of location-plate 4, and product 9 was crossed location-plate 4 and skidded off mould from the top of location-plate 4.Then cylinder 1 begins to move downward, and upset discharge rack 5 return that overturns under the effect of upset returning pull-spring 8 moves vertically downward with cylinder 1 when upset discharge rack 5 is turned to original position and returns initial position.Because limited block 6 all is equipped with in upset return pull bar 2 and upset pull bar 7 lower ends, after the position of adjusting limited block 6 made the discharge rack 5 upset returns that overturn, the pulling force of upset returning pull-spring 8 was zero.

Because the utility model has increased swing arm 3, swing arm 3 has the effect of side oscillation outside mould, when moving both vertically, upset discharge rack 5 realized horizontal motion, make product 9 in outside mould, sliding, increase horizontal movement simultaneously along the inclined-plane. the discharging angle of upset discharge rack 5 is increased, product 9 is discharged from mould smoothly.Set up upset return pull bar 2 simultaneously,, adjusted the anglec of rotation of upset discharge rack 5 very easily by adjusting the position of limited block 6.
